Do our cars have wide-band o2 sensors? Using torque Pro app
08 xkr
trying to measure AFR but maxing out ar 11.8 at wot which does not seem correct, using torque pro app

The upstream sensors are wideband, but you won't get any reading from them at full throttle. What you're seeing is the last measurement before it switches modes.
The "maxing out at 11.8" is because when you go to wide open throttle the O2 sensors are switched off and the PCM runs "WOT enrichment", this is how it works in the PanPag PCM, as i've been told.

I just want to be able to read AFR at wot properly

Long story short, you can't at WOT, the PCM "switches off" the O2 sensors and just runs off the fuel mapping. Only option is a 3rd party wideband.
Can't imagine why it would be...
When you say "reading remains unchanged" are you looking at voltage or current? The upstream sensors have a fixed voltage output, variable current.
